Seed scams are very common online, normally they are just selling some random other plant seeds.

If you want an edible banana cultivar, you must obtain a living plant, and its worth the extra money to get a high quality plant from a reputable dealer, as there are so many scams and mislabels and generally low quality plants out there.
